1. At this point general case planning can take place regarding the ultimate degree of angulations of the Wax Tube. The use of a guide pin may be useful for the case planning. The Impression Pin can be used as a guide pin.

2. Attach the Wax Tubes to the Replicas. Tighten the Wax Tubes using the Process Screw and a slot screwdriver. Determine the degree of angle of the Wax Tubes that are required to achieve an optimal entry point for the Bridge Screws. The Wax Tubes can be rotated 360 degrees to find the optimal position.

3. Mount the Wax Tube in the Waxing Tool if angulation is needed. Heat the exposed length of the Wax Tube over a flame under constant rotation.

4. Bend the Wax Tube. The Wax Tube can be bent at an angle of up to 17 degrees, depending on the design of the final restoration.

5. The maximum angle of the Wax Tube is affected by the height of the framework.

6. Screw the Wax Tubes loosely back into place on the Replicas. Make final adjustments to the rotational placement to optimize the esthetic and functional outcome of the final framework.

7. The design of the Slot Screwdriver allow access to the screw after the Wax Tube has been bent at an angle of up to 17°.

8. Adapt the vertical height of the Wax Tubes with a suitable grinding tool. The final height of the Wax Tubes should reflect the desired height of the final framework.

9. Wax-up the bridge framework according to the final design desired.

10. Remove excess wax using the Waxing Tool. The wax margin must end at least 3 mm above the apical end of the Wax Tubes.

Note: It is important to remove excess wax to ensure the correct precisioning process.

11. Finalize the wax-up and prepare the framework for investing. Invest, burnout and cast the framework according to the alloy manufacturer’s instruction.

Note: The Cresco API™ Kits are available in two versions with a prefabricated Bridge Support in titanium, or with a burnout template for casting procedures in the alloy of choice. Be sure to cast the framework in an alloy that corresponds to the Bridge Support –Titanium or to cast the Bridge Support – Burnout in the same alloy as the framework.
